'Extremalism' tickets for my wife and me were bought at La Criée box office. Any copyrighted material is included as "fair use" for critical analysis only, and will be removed at the request of copyright owner(s). Also on Facebook and Twitter.

Tim, thank you for that comment. It was quite wrong of me not to credit Valgeir Sigurdsson in the post. (I am still in Marseille and these posts are being written on the hoof; which is not something I usually do.) So I have now edited my text to credit Sigurdsson. I see that Faber Music - his publisher - has retweeted on my post, so I hope the amended version makes amends for my original omission.

I should also point out that there is a vocal part in Extremalism that is sung in this production by the 23-year-old composer, vocalist, and percussionist from Los Angeles Jodie Landau - http://wildup.la/profile/jodie-landau/
